WR Crabtree misses second day of practice

Crabtree, the 49ers’ fourth-year wide receiver who famously has never played in a preseason game, did not participate in practice today after leaving Friday’s training-camp-opening session with an apparent ankle injury.

Crabtree’s injury is not believed to be serious — he walked off the field Friday without a noticeable limp. Team spokesman Bob Lange said Crabtree “was working through something,” Jim Harbaugh’s stock response when asked about a players’ injury.

Crabtree did not attend practice. Often, injured players will work on an adjacent field with the training staff.

Crabtree is scheduled to speak with reporters Sunday for the first time since the aftermath of the NFC Championship Game. Lange said the media schedule could change and Crabtree may not be made available.

As a rookie, Crabtree missed training camp due to a contract holdout. He missed most of training camp in 2010 due to a neck injury and was absent from camp practices last year after undergoing offseason foot surgery.

In late May, quarterback Alex Smith said Crabtree’s health was a reason he was among the stars of offseason workouts.

“The thing I’m excited for him, he’s healthy,” Smith said. “And I think he’s excited about that. I think he’s feeling good about that. He shows up here, you come out and watch, he’s running better than he ever has, since I’ve seen him. Running really well out there and making plays. So it’s exciting to see. I know a lot of the new faces get a lot of the attention, but he’s doing really well here.”
